Kelly Clarkson just gave a rare sneak peek at an upcoming edition of Kellyoke, and fans can't wait for the real thing.

On the Monday, April 29 episode of The Kelly Clarkson Show, the queen of covers and Meghan Trainor will be duetting on "All About That Bass" to celebrate 10 years of the pop classic, and the host just posted a glimpse at soundcheck that has all amped up for the full performance.

The pair stood on an elevated platform in front of their microphones, with Trainor already dressed in full glam and ready for the show while Clarkson was wrapped in a cozy bathrobe. They harmonized acapella as they rehearsed, with Clarkson appearing shocked as Trainor riffed, "I'm gonna throw up," though it's no surprise to see she feels that way singing next to the woman who fans joke becomes the new owner of every cover she sings.

"I'm so nervous; I have to sing with Kelly Clarkson," she added in another clip, later calling herself "starstruck" as she watched the playback of the rehearsal, but as soon as Clarkson joined her on stage, Trainor told her to "just rail" the lyrics—and boy, did she.

It all ended with a brief look at the real deal, where Clarkson changed into a shiny silver dress with a black belt and black stilettos, the two hyping one another up as a producer counted them in.

Viewers could hardly wait for the full performance to air later that same afternoon, with one commenting, "QUEENS!!!!!! Those voices! GAH!"

"Omg this is SOOOO EXCITING! A perfect pairing of vocals, wow ??," another wrote enthusiastically, while someone else agreed that it is indeed an "incredible vocal pairing."

"Wow, they sound so good together!" another wrote.

"Gosh the energy from both ladies is amazing ??????," someone else pointed out.

We can only imagine how much bigger and bolder that energy will be when the show airs.
